Colombia police say a large illegal drug processing laboratory has been destroyed during a raid that netted six tons of cocaine valued at $180 million.
Police say they also seized tons of other material in the raid in a rural section of Meta province in the eastern part of Colombia. There are no reports of arrests.
Authorities say they believe the operation was run by a drug gang known as the Popular Revolutionary Anti-Terrorist Army of Colombia. Police say the laboratory and nearby houses could shelter at least 40 men.
The United Nations says Colombia is among the world's largest cocaine producers, and the United States is one of its most lucrative markets.
